Hello Jim, I can't help you with your Samuel B. McKnight, but I would appreciate it if you could look at my Augustine Jackson McKnight family for any similarities. Autustine J. McKnight b. 29 Mar 1818 N. Carolina m. Kessiah Yates Roper 20 Aug. 1883 Giles Co., TN Children: David Abernathy b. 1840 m. Emily Catherine Compton Samuel H. McKnight, Dr., b. Dec. 25, 2846, d. Feb. 15, 1890, bur. in Campbellsville, TN Helen Josephine McKnight, b. Mar 27, 1873 Maury Co. d. June 19, 1915 Ft. Worth, TX, m. William H. Gilmer Robert E. McKnight, nothing know about him. His children moved to California. Two other children Amanda and George W. are also mysteries. Thanks for looking, it never hurts to see if there is a connection. Juanita
